MOLDING FOR AUTOMOBILE-DOORS.

Specification of Letters Patent.

Patented Sept. 10, 1918.

Application filed April 18, 1918. Serial No. 229,349.

To all whom it may concern:

Be it known that I, JOHN T. ALLMAND,

a' citizen of the United States, residing atrequired for this operationand a steel plant is required to produce this special molding. It is theobject of the present invention to produce a molding which does notrequire the services of a steel plant and does not require to be rolledbut which can be formed from a strip of drawing steel or skelp bydrawing the same through suitable dies or forming rollers. This stripcan be made at any plant that is equipped to make ordinary tubing orsheet metal articles.

In the drawings,

Figure 1 is an elevation of an automobile door showing the position ofthe molding under the door panel.

Fig. 2 is a cross section of the molding.

Fig. 3 is a side elevation of a portion of the molding. I

The molding is formed by taking a straight strip of steel or skelp andrunning the same through suitable dies or dies and rollers to form andgather it into the configuration shown in Fig. 2. The exact formation ofthe dies or the dies and rollers need not be here given as the art inconnection with drawing metal shapes for windshield and like tubing iswell developed and no special difficulty will be encountered in drawingand gathering the skelp in the shape shown in Fig. 2.

This shape has a rough T cross section although the head of the T is notof equal width on opposite sides of the stem, nor are the head portionsto the opposite side of the stem of exactly the same angularity to thestern, there being a slight diversion from the regularity that is commonin molding for this purpose. However, the head of the T is formed withan arcuate outer surface and substantially straight under surfaces,while the stem is formed by the two sides of the skelp being doubledupon themselves. I11 short, the intermediate portion of the skelp isformed into a mushroom head in section while the outside portions of theskelp are caused to lie parallel to each other and spot-welded together.

This molding would present some great difficulties were it not for thespecial design that has been adopted to overcome the same. It would bean impossible construction as impossible to bend without collapse wereit not for the design that enables the solder to enter in between thewebs and get into the head of the T. The lower corners of the door arerounded in the usual construction, requiring bending of the molding, asshown in Fig. 1. The spot welding of the two web portions togetherallows suflicient space between the webs at certain points to let solderrun into the strip and into the concavity formed in the head of the T.TVith this solder in the head of the T the molding can be suitably bentwithout distorting the same.

The two web portions uniting to form the stem of the T serves to presentenough thickness for this portion to give a proper countersunk hole totake the ordinary screw head.

What I claim is:

1. A T molding for automobile doors formed from a single skelp foldedinto T cross section.

2. A molding for automobile doors formed from a skelp into T crosssection with the intermediate portion of the skelp forming the head andthe outside portions of the skelp uniting to form the stem of the T.

3. A molding for automobile doors formed from a skelp with theintermediate portion of the skelp forming the 'head of the T and theoutside portions of the skelp uniting to form the stem of the T andspotwelded together.

4. A molding for automobile doors formed from a skelp in which theintermediate portion forms the head of the T cross section and theoutside portions are folded together to form the stem of the T and arebored and countersunk, substantially as described.

\ 5. A molding for automobile doors, comprising a skelp formed into a Tcross sec tion With an areuate head Which has a hollow portion, theoutside. portions of the skelp being united to form the stem of the T,and means for uniting said portions that form the stem to allow amaterial to flow into the interior of the molding for use in preventingdistortion of the molding When it is bent, substantially as described.

In Witness whereof I have hereunto set my hand on the 10th day of April,1918.

JOHN '1. ALLMAND.
